You often do not even need to fire in order to run off an attacker(much less actually hit him with a bullet). Misses suffice, quite often as do poor hits, even with a "mere" .22lr.. The NRA Armed Citizen column is proof of my statement. So is Cirillo's gunfighting book. You can't shoot or intimidate anyone with a gun that you do not yet have pointed at them (and noticed, for the intimidation part) Fast draw practice has no monetary cost, can be done in your bedroom at any time. Given a laserlyte training device, or airsoft "gun" practice can help a lot with your accuracy, too. So do laser sights. You can get an electronic shooting timer for very cheap these days. It's an "app" on your smart phone, $5 or less with most makers of phones. There is no excuse for being slow with your ccw draw. Be careful to not ALWAYS fire as you draw. Always be READY to fire,yes, but do not make the actual killing-stroke a relex! The guy might surrender or flee, and you'll get videotaped killing him as he does so! You may have been mistaken about the level of the threat that you (originally) thought that you perceived. You CAN train yourself to the point that you draw if a car backfires as it drives by you, so beware of overdoing it.
